I got a box from Cigtechs and they just arrived this afternoon.
Totally initial, first impressions:
Holy cow! Got over 35 drops in the thing! OK...but with 2 heating coils, will that cause me to go through juice faster? Hmmmm....
These are very low oHms. Like, 1.2 oHms low. Keeps freaking out the ProVari. I had it set at 3.7 volts to start and kept getting the E2 error, so I have had to keep lowering it. It's now set at 3.3 volts to try and keep the error away.
As advertised, the filler seems to be very fast absorbing. That's cool.
Draw - The closest thing to a regular atty I have had with a carto yet. Still different, but I don't get the airy feeling I normally get with cartos.
IF this throat hit/feeling continues, I could see using it full time on the ProVari. Kind of defeats the purpose of having a varivolt unit if I'm stuck at 3.3 volts, but it's not like these are my only cartos/attys LOL.

On a side note: I ordered the eGo T adapter for the ProVari over the weekend, but it hasn't been shipped yet. Can't wait to see how that hits on something with more volts than an eGo.
